ok so i'm going to be buying 2 kicker comp 15s, they are 4-ohm. What i want to know is what would be a good amp for these subs at a affordable price? Also i do not know much about car audio so how many channels do i need. I know i need a 1000w amp because the subs are 500 each so would i need a 2 channel amp???? any help/advice would be appreciated and links are good 
heres the subs:
